Abstract

A method and system for establishing connection between two wireless devices. The method and system includes establishing connection authentication between the wireless devices, and measuring and the signal strength between the two devices. Predetermined values related to signal strength and signal rate change are established, and connection is allowed if the values are met.

Claims

1. A method for discriminating connection between a first wireless device and a second wireless device comprising:

establishing a predetermined connection authentication between the first wireless device and the second wireless device;

measuring signal strength of the first device;

comparing the signal strength to a predetermined signal strength threshold value;

measuring signal rate change of the first device;

comparing the signal rate change to a predetermined signal rate change threshold value; and

connecting the first device to the second device if the predetermined connection authentication, signal strength threshold value, and signal rate change value are met;

wherein

the predetermined signal strength threshold value correlates to a predetermined distance between the first wireless device and the second wireless device; and

the predetermined signal rate change threshold value correlates to a predetermined distance rate change between the first wireless device and the second wireless device.

2. The method for discriminating connection between a first wireless device and a second wireless device of claim 1 wherein measuring signal strength and signal rate change are performed by the second wireless device.

3. The method for discriminating connection between a first wireless device and a second wireless device of claim 2 wherein measuring signal strength and signal rate change are performed by the second wireless device.

4. The method for discriminating connection between a first wireless device and a second wireless device of claim 2 wherein the predetermined signal strength threshold value and the predetermined signal rate change threshold value are stored in a memory in the second wireless device.

5. The method for discriminating connection between a first wireless device and a second wireless device of claim 3 wherein the predetermined signal strength threshold value and the predetermined signal rate change threshold value are stored in a memory in the second wireless device.

6. The method for discriminating connection between a first wireless device and a second wireless device of claim 1 wherein measuring signal strength and signal rate change are performed by the second wireless device.

7. The method for discriminating connection between a first wireless device and a second wireless device of claim 6 wherein measuring signal strength and signal rate change are performed by an RF radio transceiver of the second wireless device.

8. The method for discriminating connection between a first wireless device and a second wireless device of claim 3 wherein the predetermined signal strength threshold value and the predetermined signal rate change threshold value are stored in a memory in the second wireless device.

9. The method for discriminating connection between a first wireless device and a second wireless device of claim 3 wherein the predetermined signal strength threshold value and the predetermined signal rate change threshold value are stored in a memory in the second wireless device.

10. An information handling system including a wireless device that receives signals from a second wireless device wherein the signals convey a signal strength and a signal rate change, comprising:

an RF radio transceiver capable of measuring the signal strength and the signal rate change of the second wireless device; and

a base-band circuit capable of comparing the signal strength to a predetermined signal strength threshold value and comparing the signal rate change to a predetermined signal rate change threshold value;

wherein

the information handling system is operable to a connection to the second wireless device if the predetermined signal strength threshold value, and the predetermined signal rate change threshold value are met; and

wherein

the predetermined signal strength threshold value correlates to a predetermined distance between the wireless information handling system first and the second wireless device; and

the predetermined signal rate change threshold value correlates to a predetermined distance rate change between the wireless information handling device and the second wireless device.

11. The information handling system of claim 10 further comprising:

a memory operable to store the predetermined signal strength threshold value and the predetermined signal rate change threshold value.

12. The information handling system of claim 11 wherein the memory is coupled to the base-band circuit.

13. The information handling system of claim 11 wherein the memory is coupled to the RF radio transceiver.

14. The information handling system of claim 10 further comprising:

a memory operable to store the predetermined distance and the predetermined distance rate change.

15. The information handling system of claim 14 wherein the memory is coupled to the base-band circuit.

16. The information handling system of claim 14 wherein the memory is coupled to the RF radio transceiver.
